The changes of blood viscosity, clotting and fibrinolytic system after hot bathing at 42°C and 39°C were studied on old patients admitted to the hospital for more than one year because of cerebral thrombosis.
The following results were obtained.
1) The blood and plasma viscosity as well as hematocrit value increased markedly immediately after taking a bath at 42°C. On the other hand, they slightly decreased after bathing at 39°C. Partial thromboplastin time, antithrombin III, plasminogen, α2-macroglobulin and α1-antitrypsin were also elevated just after bathing at 42°C, though they showed no significant alteration after bathing at 39°C.
2) 30 minutes after bathing at 42°C, blood and plasma viscosity and hematocrit returned to the level before bathing, while they were reduced 30 minutes after bathing at 39°C. 30 minutes after bathing at 42°C, various examinations on clotting and fibrinolytic system described above returned to the range before bathing. Prolonged prothrombin time and reduced fibrinogen were observed 30 minutes after bathing at 39°C when compared to the condition before bathing or immediately after bathing. 30 minutes after bathing, α2-macroglobulin level was found to be lower than the level before bathing, but not different from the level just after bathing.
3) The effects of bathing at 39°C and 42°C on the hepaplastin test, fibrin or fibrinogen degradation products and plasma platelets were not recognized.
4) The changes of clotting and fibrinolytic system were prominent immediately after bathing and 30 minutes after bathing at 42°C. In contrast, such changes were slight and limited after bathing at 39°C.
